This paper reports a new class of biosensors based on composite nanomaterial thin film. The composite nanomaterial film is synthesized using a simple vacuum filtration method. Using composite nanomaterial film, we can not only simplify the positioning and integration fabrication process of nanoscale materials into a functional device, but also enhance the sensing surface area significantly, which might open an opportunity to fabricate devices for ultrasensitive biosensing in a cost-effective way. Systematic measurements find that the composite film, containing carbon nanotubes (CNTs) and SnO2 nanoparticles, shows the similar field effect as that of single CNTs or nanowires (NWs) and its resistance changes upon binding to biomolecules during a bioassay process.
